Servlet 4.0, and its HTTP/2 requirement, are a key part of the Java
EE 8 technology stack. To date, Servlet 4.0 has accomplished some
significant milestones, including:

* Introducing a requirement on HTTP/2

* Mapping Discovery API

* Use of Java SE 8 default methods

These are all included in the most recent draft, the Early Draft Review. As publicly stated at JavaOne 2016, Oracle intends to complete Servlet 4.0 in calendar year 2017, with a public review draft in Q3. This statement reiterates that commitment.

These are the final results of the JSR Renewal Ballot for JSR #369.
The EC has approved this ballot.
